A sheet pan ( 120 ) having a groove ( 121 ), into which a brazing sheet is fitted, is disposed on a base ( 110 ). A slide member ( 140 ) can slidingly move along the longitudinal direction of the sheet pan ( 120 ) at a position above the sheet pan ( 120 ). A blade ( 160 ) is moved upward and downward by a micrometer ( 170 ) fixed to and supported by the slide member ( 140 ). A brazing sheet is fitted into the groove ( 121 ), and coated with an abrasive coating material. The slide member ( 140 ) is slid, with the clearance between the blade ( 160 ) and the sheet pan ( 110 ) being adjusted using the micrometer ( 170 ). As a result, a surplus of the abrasive coating material is scraped off, and the abrasive coating material becomes uniform in thickness. Thus, an abrasive coating sheet high in quality and uniform in the thickness of the abrasive coating material can be produced conveniently. |
